Calendar Rollup is a SharePoint Online Web Part built on the SharePoint Framework (SPFx). It allows users to aggregate events from multiple calendar sources — and display them together in a single unified calendar view.

• SharePoint calendars/lists - from the current site or other sites across the tenant.
• Microsoft 365 group calendars - shared team calendars from Exchange
• Personal Outlook calendars - current logged-in user's personal calendar
• Shared mailbox calendars - calendars from shared Exchange mailboxes
• External web calendars - iCal calendars subscribed through Outlook

Key capabilities:

• Month/Week/Day/Agenda calendar views
• Create, edit, delete events directly in web part
• Color coding to distinguish calendar sources

This tutorial covers installation, calendar setup, and event management. For complete technical details, see the User Guide PDF.
